Granted: 1997-05-19
Abstract: The device comprises a geared motor (17) which drives longitudinally, via a ball screw (20) and nut, the central body (22) of a moving element comprising two slides (24, 25) sandwiching the central body (22). The two slides mesh on a common pinion mounted so as to rotate freely in the central body (22). Each slide drives, via a vertical, cylindrical floating pin (34, 35, 38, 39), a control bar (9, 10) linked to a throw rod (7, 8) which is itself linked to a switch blade. The locking of an operating bar (9, 10) is effected at the end of the travel of the central body (22) by the positioning of a floating pin in a locking groove (40 to 43) of a fixed locking plate (30, 31). A mechanical fault in the transmission chain causes a relative displacement of the slides (24, 25) with respect to the central body (22), which displacement is detected by the rotation of the common pinion integrally connected to means (27) for actuating an anomaly-control contact (29).

Title: A method, a binder and a binding machine for closeing hose or bag shaped packings, primarily tubular foodstuff packings.
Inventor: KROMAN FLEMMING
IPC: B65B7/02
Filed: 1987-05-27
Granted: 1996-09-30
Abstract: The closing of tubular casings containing foodstuffs by mounting a binder on a constriction of the casing involves the traditional problem of a high waste percentage due to the binders either damaging the casing material or sliding off the constriction. A method and a binder are proposed which makes it possible to obtain a very strong clamping of the binder without damaging the casing material, and, in connection with tight plastic casings, it is even possible to provide a "super tight" closure, by ranging the constriction with an oblong cross section between opposed straight clamping beams, which are forced together so as to produce a controlled deformation flowing of the casing material.

Granted: 1992-08-10
Abstract: The apparatus for reproducing video from a laser disc without discontinuation by using two  optical  pick-ups  located  on  both sides of a disc comprises one optical pick-up (10) for picking  up the lower part of a disc, the other pick-up (20) for upper one, an optical head assembly for moving  the  two  pick-ups  in  opposite directions, for example, when the  upper  pick-up  (20)  moves  to inner position the lower pick-up (10) moves to the outer position, and a switch (30)  for  selecting  playing  signal  from  the  two pick-ups.

Title: Cellular phone of car adapter option
Inventor: JONG OK-HYON
IPC: H04B7/26
Filed: 1989-10-16
Granted: 1995-04-13
Abstract: The cellular phone is provided for controlling the RF transmitting output power and level after detecting phone stand alone status. The phone comprises a power coupler (3) input RF input signal; a car adapter (21) generating the booster installation signal connected with the high gain antenna; a tri state detection circuit (22) monitoring the car adaptor connection state and the output of the booster; and a control voltage generator (23).
